BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control method in a centralized system of a train operation management system, and more particularly to an improvement in the reliability of control output information at the time of system switching in an asynchronous dual system operation control system.

[0002]

2. Description of the Related Art A train operation management system employs a centralized system, a decentralized system, or a station distributed system in consideration of the line section scale, the degree of application, the frequency of improvement, and the risk distribution. Among these systems, the centralized system in which functions are distributed has a central command center 1, station devices 2a to 2n, and field devices 3a to 3n, for example, as shown in the block diagram of FIG. The route control device 11 and the control panel device 1
2, a display panel device 13, a central transmission device 14, an operation arrangement device 15, an operation report input device 16, and a diagram management device 17. The central transmission device 14 is a LAN 18 using an optical cable.
Route control device 11, control panel device 12, and display panel device 1
3 and the course control device 11 is connected to the Internet LA.
The operation control device 15, the operation report input device 16, and the timetable management device 17 are connected by N19.

An operation report input device 16 inputs an operation report which is change plan data to be operated systematically. The diagram management device 17 stores the operation report data input from the operation report input device 16.
The schedule is stored for a long period of time, and an operation plan schedule is created in which daily operation is performed by reflecting this operation report on a basic schedule prepared in advance. The execution plan diagram created in this way is automatically sent to the course control device 11 every day. The route control device 11 automatically sets the route of the train based on the sent execution plan diagram. The traffic rescheduling device 15 is an input device for performing a traffic rescheduling by directly changing the time line when the train cannot be operated on the schedule due to some cause. Control panel device 1
Reference numeral 2 has a route touch panel corresponding to each route of each of the station devices 2a to 2n, and performs manual intervention as necessary. The display panel device 13 displays the position and the train number of the train located on the track 4 and the state of the traffic light in order to monitor the operation status.
The central transmission device 14 is a route control device 11, a control panel device 12
Control information from the station devices 2a to 2 through the data line 5.
n, and the display information from the station devices 2a to 2n is transmitted to the route control device 11 and the like.

[0004] The station devices 2a to 2n are provided at each station for controlling the route of the train, and include a station transmission device 21 and an interlocking device 22. The station transmission device 21 transmits control information and display information from each station to and from the central transmission device 14. The interlocking device 22 controls the on-site devices 3a to 3n, inputs the status, and sends the status to the station transmission device 21.

The on-site devices 3a to 3n are composed of traffic lights, points, train position detecting devices, and the like provided along the track 4.

As shown in FIGS. 9 and 10, the route control device 11 in the central command center 1 has a main route control device 11a and a slave route control device 11b in order to avoid a system down as a redundant configuration. A multi-system configuration is adopted, and the main route control device 11a and the sub route control device 11b are connected between the systems to exchange various information.

In the asynchronous dual system operation control of the route control device 11, various systems are used for controlling the control output information at the time of system switching (automatic or manual).

[0008] As a first method, as shown in FIG.
CTC information sent from the station devices 2a to 2n via the central transmission device 14 is received in common by the main route control device 11a and the slave route control device 11b, and is control output information to be sent to the station devices 2a to 2n. Are output to the central transmission device 14 only by the main route control device 11a. Only when the slave route control device 11b is started, the master route control device 11a is started.
And state matching is attempted, and thereafter, the dual system operation is performed on the assumption that the main route control device 11a and the slave route control device 11b will operate in the same manner. This is a method in which neither collation in the system nor control output of the control output report of system switching is performed.

In the second system, as shown in FIG. 10, Cs transmitted from the station devices 2a to 2n via the central transmission device 14 are used.
The TC information is received in common by the main route controller 11a and the slave route controller 11b, and the control output information to be sent to the station devices 2a to 2n is transmitted to the central transmission device 14 by only the main route controller 11a. Output. Only when the slave route control device 11b starts up, the status information is received from the master route control device 11a so as to match the statuses. Thereafter, the shift information of the train is used as the collation information. For the control output of the control output information at the time of system switching, the control output information is transmitted / received from the main route control device 11a to the slave route control device 11b separately from the shift information during the collation operation.

[0010]

The first method is based on the assumption that the main route control device 11a and the sub route control device 11b will operate substantially the same. Since the control output information is output without collating the operation states of the route control device 11a and the slave route control device 11b,
Since the operation status of the slave route control device 11b is not known, there is a problem that there is no guarantee that the output of the control output information is correctly continued after the timing of the automatic or manual system switching.

In the second method, the control output information of the master system and the control output information of the slave system are compared. When the system switching occurs and the old slave system becomes the new master system, the control output information of the old system becomes the new master system. This is to prevent output leakage. After outputting the control output information to the central transmission device 12 in the master system, the control output information is output to the slave system. When the control output information is received by the slave and the control output information on the traffic signal is also generated by the slave, it is determined that the operation is performed normally and the registration information is canceled. When the control output information of the main system is received, if the control output information of the traffic signal has not yet been generated in the slave system, this information is registered. If the control output information on the traffic signal has been received from the master and registered at the slave control output information output timing, it is determined that the operation has been performed normally and the registration information is canceled. After the registration of the control output information of the main system or the registration of the control output information of the slave system, if the control output information of the other party does not occur even after a certain period of time has elapsed, and the system is a slave system, the registration information is canceled. At the timing when the sub system becomes the main system by system switching, the control output information registration table is searched and the registered control output information of all traffic signals is re-output so that there is no output omission of the control output information. This is the method to deal with.

[0012] However, in the following cases, there are rare cases where the control output information relating to the traffic signal is output again even though the output is normal, or the output is output even though the control output is not performed. . First, since the main system and the slave system operate asynchronously, depending on the timing at which the on-line information and the traffic signal status information are taken, the slave system takes in the display information of the traffic signal which is being displayed by the control information output of the main system. There are cases. In such a case, since there is a standard logic that automatic route control output is not performed with respect to the traffic signal that is already displayed, no slave control output information output timing occurs. When the system switching occurs in such a state, the control output information related to the traffic signal is output again.

Second, at the time of manual intervention during automatic operation, the manual intervention data from the control panel 12 is taken in asynchronously by the main system and the slave system. When the signal is delayed and the automatic signal output timing is detected, the signal is controlled and output to the slave system, and this information is passed and registered. If the input of the slave route control device is delayed, the control output from the master system is not made and does not reach the slave system. Even in this case, control output information is generated and registered in the slave system. If the system switching occurs in such a state, the control output information relating to the traffic signal is output again.

Third, control output information from the main system is hard-coded.
If system switching occurs in a state where reception was not possible due to hardware or software factors, control output information related to the traffic signal is output again.

The present invention has been made in order to solve such a problem, and provides a more reliable operation control method of control output information at the time of system switching in an operation control system of an asynchronous dual system configuration. It is intended for.

[0016]

An operation control method according to the present invention is directed to an asynchronous double system operation control method having a main system and a sub system path control device, wherein control output information of each traffic light is controlled by a main system path. output control unit registers the control output information of each traffic signal in the traffic signal information table in the main system and the slave of the route control device when the output timing of the control output information, each traffic
The CTC display information indicating the content of the signal is received by both the master and slave route control devices, and the master and slave route control devices detect the change of the traffic signal by the CTC display information input in common. Then, the registered control output information of the corresponding traffic signal is canceled, and the control output information of the registered traffic signal is not output at the timing when the slave system becomes the main system due to the system switching and the registered control signal information is output again. It is characterized by the following.

[0017]

According to the present invention, as the comparison information in the asynchronous duplex system having the master route control device and the slave route control device, the asynchronous output is used as the control information of the control output information.
The comparison information can be obtained without using the control output information of the partner system, which may not be obtained due to heavy system operation control, or may not be obtained due to the hardware of the inter-system interface or software failure. The information is obtained from CTC display information that is commonly input to the main route control device and the slave route control device. That is, the control result of the control output information of the traffic light is detected as the present change of the traffic light. Then, at the timing when the sub system becomes the main system by system switching, the control output information of the traffic signal for which the present change cannot be obtained is re-outputted, thereby preventing leakage of the control output at the time of system switching.

[0018]

FIG. 1 is a block diagram showing a dual system operation system of a route control device in a train operation management system according to one embodiment of the present invention. The train operation management system is exactly the same as that shown in the block diagram of FIG. 8, and includes a central command office 1 having a route control device 11, a central transmission device 14, and the like, and station devices 2a to 2 provided at each control station. 2n and field devices 3a to 3n such as traffic lights. As shown in FIG. 1, the route control device 11 adopts a dual system configuration of a main route control device 11a and a slave route control device 11b in order to avoid a system down, and a main route control device 11a. The slave route control device 11b is connected between the systems to exchange various information. The main route control device 11a and the slave route control device 11b are connected to the central transmission device 14 by a LAN 18 using an optical cable.

In the asynchronous dual system operation control system configured as described above, the main route control device 11a and the subordinate route control device 11b are used as input information to each of the station devices 2a to 2a, as shown in FIG. 2n together with the CTC display information sent via the central transmission device 14, and the respective station devices 2a to 2c.
The control output information to be sent to 2n is output to the central transmission device 14 only by the main route control device 11a. When the slave route control device 11b starts up, the master route control device 1
1a, the state information is received, the states are matched, and thereafter, the main route control device 11a and the slave route control device 11b
The CTC information received from the central transmission unit 14 as the operation state collation information, specifically, the train shift information combining the present change of the traffic light and the falling state of the inner track circuit, is used to exchange collation information between systems. Confirmation has been strengthened.
The transmission and reception of the collation information is performed in consideration of the time of the interface failure by transmitting and receiving the train shift information using the dedicated line and also transmitting and receiving the train shift information by using the LAN 18. Prevents the occurrence of collation mismatch. In addition, the timing of the train shift information is the signal information when the traffic signal of the on-site device changes from the present G indicating progress to the present R indicating stop for both the in-field shift and the departure shift, and when the train enters the inner track. Train shift information is generated based on the on-rail information.

As shown in FIG. 2, the control output information generated by the main route controller 11a and the slave route controller 11a includes traffic signal information tables 6a to 6n for the respective traffic signals.
Is managed as signal information using the signal data table 6 having Each traffic light information table 6a to 6n
Are used / unused, signal information and monitoring timer value. Used / unused indicates whether or not the traffic signal information of the corresponding traffic signal is registered, the traffic signal information indicates the content of the control output information of the controlled traffic signal,
The monitoring timer value is a timer value for monitoring train shift information generated by the own system or the other system.

In the above-mentioned train operation management system, when the secondary route control device 11b is started up and the asynchronous dual system operation control is performed, the signal control is performed by the primary route control device 11a or the secondary route control device 11b. 3 and 4 show the operation when outputting the output information and the operation for confirming the traffic light display information.
This will be described with reference to the flowchart of FIG.

The main route control device 11a and the sub route control device 11b register the signal information of each signal in the signal data table 6 at the time of outputting the signal control output information (step S1). At the same time, a monitoring timer is registered based on the monitoring timer value (step S2). When the own route is the main route control device 11a, the traffic signal control output information is output to the central transmission device 14 (steps S3 and S3).
4). For example, as shown in a time chart of FIG. 5, a timing T ₁ for outputting signal control output information of a signal.
In some cases, the traffic signal information of the traffic signal is registered in the traffic signal data table 6 as a traffic signal information table 6a as shown in FIG. 2, and the registered traffic signal control output information is output from the main route control device 11a. Next traffic light of the traffic signal control output information for outputting the timing T ₂ times the the signal information te the signal information similarly traffic - registered as table 6b, and outputs a traffic signal control output information from route controller 11a of the main system. Hereinafter, the above processing is repeated at the timing of outputting the traffic light control output information of each traffic light.

The confirmation processing of the traffic light display information is carried out by referring to FIG.
As shown in the flowchart of FIG.
a and the slave route control device 11b share a common input C
The TC display information is confirmed, and when it is detected from the input CTC display information that the traffic signal has changed from the signal R indicating stop to the signal G indicating progress (step S1).
1) Search the traffic light data table 6 and confirm whether or not the traffic light control output information of the traffic light concerned is registered (steps S12 and S13). As a result of this check,
If the traffic light control output information of the traffic light is registered, it is determined that the traffic light is normally controlled, and the registration information is canceled (step S14). For example, after outputting the traffic signal control output information registered in the traffic signal information table 6a, when the control result of the corresponding traffic signal is detected by the CTC display information, it is determined that the traffic signal is normally controlled, and the time chart of FIG. As shown in (5), the registration information of the traffic light information table 6a is canceled. This confirmation process is sequentially repeated.

The main route control device 11a and the slave route control device 11b perform the output processing of the traffic light control output information and the processing of confirming the traffic light display information as described above, and at the same time, periodically perform the traffic light de-encoding. -Searching the table 6 and repeating the cycle monitoring process for checking whether the signal control output information is normally output. The operation of this period monitoring process will be described with reference to the flowchart of FIG.

In the cycle monitoring process, monitoring after output of the traffic light control output information, detection of occurrence of system switching, and re-output of control output information accompanying the monitoring are performed. In the monitoring process after the output of the traffic light control output information, the traffic light data table 6 is periodically searched to check whether the traffic light information is registered (step S21). If the control output information of the traffic light is registered in the traffic light data table 6, the monitoring timer is decremented (steps S22 and S23). For example, when the traffic light information table 6a is registered in the traffic light data table 6, it is checked whether the monitoring timer value registered in the traffic light information table 6a has been reached. If the signal information tables 6a to 6n are registered in the signal data table 6 as shown in FIG. 2, this check of the monitoring timer is repeated for each signal information table 6a to 6n. Result of repeating this monitoring process, for example time chart of FIG. 7 - as shown in bets, signal information te - passed by monitoring timer value t ₁ from the output timing T ₁ of the traffic signal control output information registered in table 6a If the control output result of the corresponding traffic signal cannot be obtained (step S24), and if the own system is the main system (step S25), the traffic signal control output information registered in the traffic signal information table 6a is re-outputted. Then, the registration information of the traffic signal information table 6a is canceled (step S27). After performing the above monitoring process for all the traffic signals registered in the traffic light data table 6 (step S22), it is detected whether or not system switching has occurred. It is confirmed whether the system is a new main system after system switching (step S28). If the own system is the new main system after system switching, then the traffic signal data
The control output information of all the traffic signals registered in the table 6, that is, the control output information for which the control result of each traffic signal is not obtained as the present change of the traffic signal, is re-output (step S2).
9) Cancel the registration information (step S30).
As described above, when the system is switched, the control output information for which the control result of the traffic signal is not obtained as the present change of the traffic signal is re-output, so that the output omission of the control output information at the time of system switching can be prevented.

[0026]

As described above, according to the present invention, in an asynchronous duplex system having a main route control device and a slave route control device, the control result of the control output information of the traffic signal is used to indicate the change of the traffic signal. As a result, the control output information of the traffic signal for which no change can be obtained at the timing when the slave system becomes the master system due to system switching is re-output to prevent leakage of control output at the time of system switching, so asynchronous The reliability of the dual system operation control can be further improved.
